I’m not a garage sale expert, but having done a few with a friend and one on my own, there are some things that can make it easier and, of course, you'll sell more stuff. Summer and early fall are prime yard sale times so plan yours soon.
1. Bigger is better. People tend to stop, look and buy more when there is more to see. With a small stash, you’ll most likely get passed by. Get your friends and neighbors to put items together so you can have a larger sale.
2. Use a team approach. Check to see if other people in your area are planning a sale. Set your sale on the same day since if there are other yard sales going on, you should see more traffic.
3. Make your signs clear. A handwritten sign is OK if the lettering is bold and clear. Adding a balloon to the sign and then 'mark' a path with more balloons and signs at major intersections. Lettering the sides of an old box helps if you can't tape signs anywhere. You can also weight them down. Pick up your signs at the end!
4. Know the value if what you're selling. For large items and antiques - even furniture- check eBay, CraigsList or other source and see what you should be able to get for those items. Even knowing the value of used toys, electronics and appliances will help you negotiate with a buyer.
5. Keep your money Safe. Since you should be moving around talking to people and showing them how things work, you want to have an easy way to keep it accessible and safe. A fanny pack works well, as does an apron or a coupon holder clipped to a belt.
6. Start with change. Before the sale, stock your money pouch/apron with one and five dollar bills as well as a few dollars worth of quarters.
7. Good presentation is critical. Make sure people can see what you’re selling. Pull items from packaging so they can be seen. Organize "like" items together so people can browse and select. Similar "like" items in a multi-family sale should be grouped together for more impact.
